I couldn't find any form of firmware online for this TV. I don't think its even possible to install any form of software on the system by yourself, there are no network or USB interfaces available on the TV, only a "service socket" which is exclusively for authorized service partners, according to the manual.
Your best bet would be to contact Medion directly, though I doubt its worth it for a TV from 2006.

I want to refund this tv. I need dump for flash AM29DL164DT, because the original software was broken.
At present, with dump for Tevion 42" PDP tv began to work on but 3/4 picture width.
I do not have access to the service software, so I write here for help.
